LAWN-RAKE.

SPECIFICATION forming part of Letters Patent No. 757,123, dated April12, 1904. Application filed June 19, 1903- Serial No, 162,255. (Nomodel.)

To all whom it may concern:

Be itknown that I, OTTO KAMPFE, acitizen of the United States, residingin New York, borough of Brooklyn, and State of New York, have inventedcertain new and useful Improvements in Lawn-Rakes, of which thefollowing is a specification.

This invention relates to an improvement in lawn-rakes, whereby they canbe passed easier over the lawn without entering into the soil andinjuring the roots or tearing up the sward, the end teeth acting in thenature of guides or shoes for the rake, as weed -extractors, and alsofor marking off the width of the furrows when planting certainvegetables; and for this purpose the invention consists of a lawn-rakethe end teeth of which,

are provided with prongs which are bent backwardly and are somewhatlonger than the intermediate teeth, so as to lift the intermediate teethslightly above the soil of the lawn.

The invention consists, shaped recess formed by the sharp-corneredprongs for the unrooting of the weeds in the lawn, as will be more fullydescribed hereinafter and finally pointed out in the claims.

In the accompanying drawings, Figure 1 represents a perspective view ofmy improved lawn-rake. Figs. 2 and 3 are perspective views of the endportion of the rake, drawn on a larger scale, so as to show clearly thebackwardly-curved prongs of the end teeth; and Fig. 4 is a detailperspective view of one of the end teeth.

Similar letters of reference indicate corresponding parts.

eferrings to the drawings, A represents an ordinary hand lawn-rake, anda the teethof the same. The end teeth a are provided at their lower endsor points with two backwardly-curved prongs 6, that are forked so as toform a Vshaped recess (Z between them and which are provided withflattened ends e. The prongs b are made to extend at a greater depththan the lower ends or points of the intermediate teeth, so that whenmoving the rake over the lawn the curved prongs Z) of the end teeth aform guides so that the intermediate teeth a will be lifted slightlyshaped recess between the further, of a V.

above the soil without tearing up the roots or sward. The prongs of theend teeth form, so to say, shoes on which the rake is moved over thelawn, so that the intermediate teeth take up the leaves, extractedweeds, cut grass, and other matter to be removed from the lawn, whilenot tearing up the soil or injuring the sward. The prongs forming theV-shaped recess between the curved prongs of the end teeth are somewhatsharp-cornered and have the further advantage that objectionable weedscan be pulled up or unrooted from the lawn, which is accomplished byengaging the weed by the apex of the V-shaped recess of the end teeth,twisting the rake, and simultaneously lifting the sameso as to pull outthe weed, which is held at the apex of the V- prongs. The prongs of theend teeth may also be used for marking the furrows in the soil whenplanting certain vegetables, the prongs forming furrows of certain widthfor this purpose. The prongs are preferably made integral with the endteeth by forging or otherwise and form a very inexpensive but usefulimprovement on the ordinary lawn-rakes.

H aving thus described my invention, I claim as new and desire to secureby Letters Patent- 1., A lawn-rake, having a plurality of teeth, thepoints of the end teeth of which extend somewhat beyond the points ofthe intermediate teeth, and forked backwardly-curved and flattenedprongs at the point of the end teeth, substantially as set forth.

2. A lawn-rake, havinga plurality of teeth, the lower ends of the endteeth of which are provided with backwardly-curved and flattened prongsthat are located slightly below the lower ends of the intermediateteeth, and a V-shaped recess between the prongs, substantially as setforth.

In testimony that I claim the foregoing as "my invention Ihave signed myname in presence of two subscribing witnesses.

OTTO KAMPFE.
